Question: Which models come with fuel tanks equipped with straight tubes?  

Answer: The three line safety stopper was introduced into production across the VMAR ARF line in mid 2004. The straight tubes were also phased in at that time. The tubes can be bent from straight or left as is depending on the application.

Kits introduced prior to mid 2004 may have Assembly and Operations Manuals showing the older two line tank with no safety stopper and bent tubes. The new tank, safety stopper and straight tubes have superceded the assembly shown.
